Apart from this, Figure REF  depicts the qualitative evaluations of the proposed framework on the SIXray [1]} dataset. In this figure, the first row shows examples containing one instance of the suspicious item, whereas the second and third rows show scans containing two or more instances of the suspicious items.
Here, we can appreciate how accurately the proposed scheme has picked the cluttered knife in (B). Moreover, we can also observe the extracted chopper (knife) in (D) despite having similar contrast with the background. More examples such as (F, H, and J) demonstrate the proposed framework's capacity in picking the cluttered items from the SIXray dataset [1]}.
